More seriously, it could have been a bidding frenzy but the sequence of bids doesn't support that idea very well. Perhaps the three or four high bidders want to shoot roll film and have cameras with spring backs. That limits them to Adapt-A-Rolls; Calumets, and 6x9 C2Ns are uncommon; and horribly expensive things like the Sinar back.

The wierd thing is somebody bought a Calumet C2 I think that's the model name for about $70 less then 1 hour after the adapt-a roll went.

Nick, most of the Calumets are 6x7s, not 6x9s. All AARs are 6x9s. And, although I don't know if they deserve it, the random search on the C2 will turn up bad news about reliability and frame spacing. AARs' frame counters don't always advance the number properly, but even when half-functioning they give good and consistent spacing.

Besides, it often happens on eBay that auctions for much the same thing close roughly simultaneously at very different prices. I'm an economist, and I know well that when obtaining and processing information is costly then the optimal level of optimization is less than full. Herb Simon got a Nobel for that insight.
